Tanya is the name of an individual conceived by Alfred Ashford's neurosis. In 1983, Alfred made it his duty to reanimate his cryogenically-preserved sister, Alexia after fifteen years. By 1998, however, he had adopted a female persona he identified as Alexia. Tanya was created in order to explain who it was he was to save.

She is mentioned in two audio sample being wished a happy 13th birthday in 1983, and in 1998 again being wished a happy "13th birthday for the 15th time" by both "Alexia" and Alfred.
